摘要

用BBK模型和修正后的BBK模型, 计算了入射能为15.6 eV, 17.6 eV, 25 eV, 40 eV的电子入射电离氢原子的二重微分散射截面. 本文把计算结果与测量的实验结果进行比较, 分析了截面的结构, 系统研究了交换效应对截面的贡献.

关键词:

The double differential cross sections for electron impact ionization of hydrogen at incident energies of 15.6 eV, 17.6 eV, 25 eV and 40 eV are calculated by use of BBK model and modified BBK model. The results of the present work are compared with the absolute experimental date. The structure of the cross sections is analysed and the contributions of exchange effects to corss sections are discussed.
